Odpowiedź:
34% z 300
300 = 100%
x = 34%
korzystajac z proporcji
x/300 = 34/100
x = 34/100 * 300 = 34 * 3 = 102
56% z 4600
4600 = 100%
x = 56%
x/4600 = 56/100
x = 56/100 * 4600 = 56 * 46 = 2576
80% z 12
12 = 100%
x = 80%
x/12 = 80/100
x = 80/100 * 12 = 4/5 * 12 = 48/5 = 9 3/5
10% z 440
10% = 0,1
x = 44
23% z 4500
4500 = 100%
x = 23%
x/4500 = 23/100
x = 23/100 * 4500 = 23 * 45 = 1035
89% z 6100
6100 = 100%
x = 89%
x/6100 = 89/100
x = 89/100 * 6100 = 89 * 61 = 5429
